What the Data for This Category Looks Like
Data sources for commercial real estate research reports primarily include regional market reports released by industry associations, internal lease record data from commercial operating enterprises, and business district analysis documents from third-party research institutions. Update cycles include monthly single-project rent monitoring, quarterly regional market reviews, and annual industry trend white papers.
Document structures typically contain five modules: core summary, regional business district overview, single-project lease data, tenant profile, and future outlook. Fields covered include rentable area per project, daily rent, the ratio of vacant area to total rentable area, foot traffic, and more. Core units are square meters, daily rent, and visits.
Constraints Imposed by These Characteristics on Citation Source and Traceability
The multi-source, dispersed nature of commercial real estate research report data requires traceability to link unique identifiers across multiple data sources, avoiding ambiguity from single-source annotations. Data with different update frequencies requires corresponding timestamp annotation rules. Monthly monitoring data must include collection dates, while annual white papers must include release dates.
The multi-module document structure requires traceability to pinpoint specific chapters and paragraphs, rather than just annotating the full document. The diversity of fields and units requires traceability to simultaneously display field definitions and units, preventing confusion from differing statistical specifications across data sources.
Configuration Settings
| Configuration Item | Recommended Value | Rationale for This Value |
|---|---|---|
topK | Top 6-8 entries | Commercial real estate research reports have relatively long single-piece content. Sufficient paragraphs must be retrieved to cover core arguments, while avoiding interference from redundant information |
scoreThreshold | 0.75-0.85 | Commercial real estate data has strong professional characteristics. A higher similarity threshold is needed to filter out irrelevant content, while preserving niche data within the field |
sourceDisplayMode | "Full path + paragraph number" | Commercial real estate research reports include multi-chapter submodules. The chapter and specific paragraph location of the source document must be clearly marked |
enableSourceTimestamp | Enabled | Different data sources have different update frequencies. The specific time of data collection or report release must be marked to meet industry traceability requirements |
chunkSize | 800-1200 characters | The core information per paragraph of commercial real estate research reports is relatively long. Excessively long segmentation will reduce retrieval accuracy, while excessively short segmentation will damage data integrity |
The parameter values provided on this page are common recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Phenomenon: A red error prompt appears in search results after configuring
sourceDisplayModeas "Full path + paragraph number". Cause: TheenableSourceTimestampparameter is not enabled, or the segment number does not match the actual document’s chapter structure, resulting in failure to generate traceability links correctly. - Phenomenon: In a workflow based on question classification, only the first user question returns knowledge base citations, while subsequent questions have no citation content. Cause: Persistent transmission of global variables is not configured in the workflow, or the knowledge base retrieval node is not correctly bound to the
datasetIdparameter, resulting in subsequent nodes being unable to call the target commercial real estate knowledge base. - Phenomenon: No knowledge base citation identifiers are attached to the AI’s output content, and raw text is displayed directly. Cause: The
enableSourceCitationparameter is disabled, or the system prompt does not explicitly require embedding citation sources in the response, resulting in retrieval results not being integrated into the final output.
How to Confirm the Configuration Is Complete
- Initiate a targeted search for a single commercial real estate research report, and verify that the returned results include traceability information such as document chapters, paragraph numbers, and timestamps.
- Test multi-turn dialogue scenarios to confirm that knowledge base citation content is attached to the returned results for each round of questions.
- Check the global variable binding configuration to confirm that the
datasetIdparameter is correctly referenced in all retrieval nodes of the workflow. - Adjust the similarity threshold parameter to verify that the relevance of the returned results meets business expectations, with no irrelevant content included.
